Title: Water-base sizing agent for glass fiber
Inventor: TAMAKI YOSHIFUMI
IPC: C08L75/00
Filed: 1991-05-10
Abstract: PURPOSE:To obtain a polyurethane resin water-base sizing agent for glass fiber reinforced plastics which gives little production of thermal decomposition gas during high temp. molding. CONSTITUTION:A prepolymer is obtd. by the reaction of polyester of neopentyl glycohol/terephthalic acid/adipic acid, neopentylglycohol, and isophorone diisocyanate, into which polyoxyethylene.polyoxypropylene glycohol is added as n emulsifier to emulsify the prepolymer. Then the prepolymer is treated with hydrazine hydrate to extend chains and to obtain a polyurethane water-base dispersion. Into this dispersion, gamma-aminopropyltriethoxy silane, a lubricant and water are added to obtain a sizing agent for glass fiber. This sizing agent is deposited on glass fiber and dried to obtain the sizing glass fiber. This treated glass fiber hardly causes cracks or napping, is excellent in affinity to resin, and gives almost no production of thermal decomposition gas during molding. The glass fiber reinforced thermoplastic resin is excellent in color, strength and appearance.

Title: Power on clearing circuit
Inventor: KADOWAKI TADAO
IPC: H03K17/22
Filed: 1980-08-01
Abstract: PURPOSE:To avoid the erroneous production of the clear signal to the fluctuation of the power supply voltage caused by the switching of load, by performing the switching of the time constant through a rectifying element in accordance with the charging and discharging of a capacitor. CONSTITUTION:When a power source 14 is applied, a capacitor 15 is charged by the source 14 and a diode 18 is set forward. Thus the potential at the point 20 is stabilized at VSS from VDD at the moment of application of the source 14 and after a time of resistance 16 X capacity 15. A transient phenomenon of the potential at the point 20 is detected, and the waveform shaping is carried out by an inverter 19 to obtain a clear signal. On the other hand, the charge of the capacitor 15 is discharged with an increment of the load. In this case, the diode 18 is set backward, and the time constant is set to (resistance 16 + resistance 17) X capacity to increase. As a result, the reduction of the potential can be extremely reduced at the point 20 and cannot exceed the logic level of the inverter 19. Thus no clear signal is produced.

IPC: C25D13/00
Filed: 1989-04-25
Abstract: PURPOSE:To partially change the coating film thickness and to conduct economical electrodeposition coating by covering the region of a material where a coating film is to be thinly formed with a covering member away from the region. CONSTITUTION:When the body of an automobile is undercoated, for example, the front floor panel b1 as the region of the body (to be coated) where a coating film is to be thinly formed is covered with the covering member 7 at a specified distance (e.g. 10-50cm) from the region.

Abstract: PURPOSE:To attain sure fault processing for the occurrence of a fault in an exchange and a fault in a transmission line by constituting the system with a management device connected to plural exchanges to unify the management of a fault state in an exchange network. CONSTITUTION:A ring management device (RME) 1 makes fault supervision with all ring exchanges (RAE) 2 connected in a ring via a fault supervisory path 5 and a fault of a transmission line 3 and the RAE 2 is detected through the fault supervision. If the RAE 2 has a fault, since a replay of a health check response 9 to a health check command 8 in a period of a time t1 sent from the RME 1 is not returned, the RME 1 regards the RAE 2 as a fault after a prescribed time t2 and it is used as a RAE fault generation notice 11 and informed to all the RAEs 2 except the faulty RAE 2.

Abstract: PURPOSE:To prevent the production of an undesired radiation radio wave when a trap circuit eliminating a disturbing wave in a selected channel is provided in the high frequency receiver. CONSTITUTION:A radio wave inputted from an antenna is fed to a frequency mixer 16 via a filter 11, an input tuning circuit 12, an RF amplifier 14, a dual tuning circuit 15, and a trap circuit 13 and an intermediate frequency is generated through the mixing of an oscillated output from a local oscillator 17.
